Patented Dec. 16, 1 930 JOSE SERBA.RABERT, 0F BARCELONA, SPAIN SPINNINGAND TWISTING MACHINE Application filed May 3, 1928, Serial No. 274,876,and in. Spain May 12, 1927.

In machines for continuous spinning and twisting two different methodsof causing the rotation of the spindles are employed. In the one thismovement is transmitted from a common drum to each of the pulleysmounted upon the spindles, by means of cords or" upper part of thesection of the support serves for the reception of a series ofequidistant holes one for each spindle, the mounting of the spindlebeing effected by means of a nut which carries the spindle and whichpresses on the under face of the upper wall of the support or frame.Upon the lower part of the support or frame are mounted the parts whichserve to transmit the reciprocating movement to the balance or ringssupport.

In the second case the support or frame may take a variety of forms, butthey offer various disadvantages in the mounting of the driving wheelswhich gear with the wheels mounted at the lower extremity of eachspindle. To avoid these disadvantages in the simplification of themounting and adjustment, means are provided according to the inventionfor suspending from the upper part of the support a common spindle uponwhich are mounted the driving wheels and their supports. For thispurpose a series of holes are provided of greater diameter than theextremities of the said supports which are provided with bolts havingtwonuts between which is engaged the upper part of the frame or supportcarrying the spindles. In this manner there is obtained the necessaryvertical and horizontal adjustments of another adjacent section.

With these modifications and for the adaptation of a new system ofspindles the frame or support carrying the spindles is modified and forthe purpose of protecting the operatives against accidents and at thesame time to facilitate erection there is placed at the rear over theopening in the supporting frame a cover secured by means of screws bywhich the access of dust and fibres from the spinning room into thecavity within the supporting frame is avoided.

In order that each of the parts of the supporting frame carrying thespindles, of which the machine is composed, may be securely connected tothe adjacent part, each section of the supporting frame is provided witha labyrinthine channel on its end faces which in building up the framemay be filled with a plastic substance or cement or with metal ofrelatively low melting point, whereby the respective parts or sectionsof the supporting frame may be conveniently and effectively connected.The lower part of the supporting frame carrying the spindles generallytakes the form of that first described in which the transmission ofmovement to the spindles is effected by means of cords or hands.

In the accompanying drawings is represented a construction according tothe invention by way of example.

Figure 1 is a sectionof the supporting frame carrying the spindles, inwhich is indicated a spindle, a support for the driving spindle, and thedriving wheel.

In Figure 2 two sections of the driving spindle are represented with thedriving wheels, the separating sleeves, the spindle driving supports andthe means provided at the extremities of the sections of the drivingspindle for their connection.

Figure 3 indicates the manner in which two consecutive or adjacentsections of the supporting frame may be connected.

Figure 1 is a section on the line 44 of Figure 3.

In Figure 1, the part 1 represents the exterior form of a spindle whichis mounted on the supporting frame 2 by its introduction through thehole 3 and by the nut 4 which presses against the interior face of thesupport. The endless worm or wheel 5 is mounted atthe lower end of thespindle and receives its movement by engagement with the correspondingdriving wheel ,6 mounted uponthe common driving spindle 7. This latteris suspended in the support 8 by means of the ball bearing 11, and thering of the support- 8 is split at 9 for the engagement of the ballhearing, and is caused "tightly'to engage the exterior ring of the ballbearing by means of a screw-threaded pin '10.

The support 8 is provided with a screw threaded part 12 upon which screwthe nuts 14, 14. The part 12 passes through a hole 13 of larger diameterin the upper part of the supporting frame 2 and is fixed in position bythe nuts 14, 14. r

The protecting cover 16 is mounted in position by means of screws 15,15.

Figure 2'is a longitudinal section of the common spindle 7 carrying thedriving wheels 6 and serving for two adjacent or consecutive parts ofthe machine. In the figure the references 2, 8,11, 12, 13, '14, app'l tothe same parts as in Figure 1.

The wheels 6, 6 are mounted in their position at the same distance apartas the spindles 1 by the tubes or sleeves 17 which at the same timeserve to secure the wheels 6, 6 rigidly to the common driving spindle"?by means of the nuts 19, 20 mounted: upon the screwthreaded extremities18, 18 of the adjacent sections of thespindle 7. The nuts19, 20 areprovided to form a coupling between the saidsections of the spindle 7and for-the purpose one of them, 19, is provided, for example, with aprojection or tooth 21 capable of engaging freely in a correspondingrecess 22 in the 'nut'20 so as to permit any variation due to expansionof the adjacent sections of the spindle 7 that may occur and to ensurethat all movements of one section of the spindle are transmitted to theother.

In Figure 3 the figures2, 15, 16 are applied to the same parts as inFigures 1 and 2. The 7 line 25 a closed channel is formed by the adjacent parts, serving for the introduction by suitable means of ajointing cement or metal. 24. 7

I claim 1. In machines for continuous spinning and twisting having aplurality of spindles, a driving spindle and means for mounting thedriving spindle, comprising a supporting frame for the spindles,supports for the driving spindle, which supports are provided withsuspension parts which traverse the supporting frame through holesgiving clearance,

whereby lateral adjustment of thesupports may be effected to-facilitateadjustment of the engagement of the gears by which transmission ofmovement to the spindle is effected, and screw-threaded nuts screwingupon the said suspension parts and between which the supporting frameis-engaged for the retention of the supports in the relative position ofadjustment.

2. In machines for continuous spinning and twisting as specified inclaim 1, a driving spindle in sections and pans of nuts respecdescribed.
